IMPROVEMENT IN SH|NGLE=MACH!NES.

Specification forming part of Letters Patent No. 124,057, dated February:27, 1872.

Specification describing acertain Improved Shingle-Machine invented byJEROME V. GUE and GEORGE I. ANDERSON, of North Western, in the county ofOneida and State of New York.

The invention will first be fully described and then clearly pointed outin the claim.

Figure l is a side elevation of our improved machine. Fig. 2 is a planview. Figs. 3 and i are transverse sections.

Similar letters of reference indicate corresponding parts.

A represents a large horizontally-revolving saw, mounted at the centerof a suitable frame, B, on the top of the mandrel (l. D represents thecarriage, which is intended to carry a bolt at each end, and feed one upto the saw at one side at the same time it is moving the other away atthe other side, the said carriage being arranged over the saw, andcarrying the bolts above it as the shingles are cut off the under sidesand discharged down the chutes E. The carriage is actuated by the wheelF and connecting-rod G. This carriage is wide enough to receive thebolts endwise between the sides and the holding-dogs H I, one of which,H, is permanently fixed on the carriage, and the other is part of a longbar, pivoted at K to swing toward and from the fixed dog for engagingand releasing the bolt. It is pressed against the bolt by a spring, L,and away from it by the inclined end M acting on a stud-pin, 0, justprevious to the end of the movement of the bolt away from the saw. Thisreleases the bolt at the ends, and lets it fall upon the frame P, whichstands as much below the saw as the thickness of one shingle, so thatthe fallin g of the bolt on said frame sets it for the next cut. Thebolt is confined again between the dogs as soon as the carriage movesbackward and the incline H is drawn away from the pin 0. In order toshift the bolts for alternately cutting heads and points, the frames Pare mounted at the center between the sides of the carriage on a rod, Q,so as to be tilted at the ends for holding the bolts high at one end andlow at the other, alternately with the movements of the carriage. Aspring, It, is arranged with each frame, to constantly liftone end, anda square revolving-bar, S, with two high and two low sides, is providedfor lifting the other end of the frame against the spring. This bar isprovided with four points at one end, by which it is to be turned aquarter of a revolution at each double movement of the carriage, bymeans of a pawl, U, alternately bringing one high side and one low sideof the bar under the tilting-frame, by which the bolt is held inrelation to the saw, so that heads and points will be alternately cut ateach end. A frame, P, with its tilting adjuncts, is arranged at the twoopposite sides of the saw, one for each bolt, and they are both actuatedby the pawl U, which comes in ,contact with the points T just previousto the end of the movement by which the bolt is fed to the saw, andadjusts the frame ready for receiving the bolt at the end of thebackward movement at the time the jaws are opened by the incline Mcoming in contact with the pins 0. The pawl U is shifted by the pins Von the carriage coming in contact with pin W. By this plan the feedingand setting apparatus is reduced to the minimum of simplicity andcheapness.

Having thus described our inventionfwe claim as new and desire to secureby Letters Patent The pivoted frame P, combined with spring R, points T,pins V V, pawl U, and rotary bar S, constructed as and for the purposedescribed.
